HARRY II. BECKWITI-I, OF BROOKLINE, MASSACHUSETTS COATING DEVICEApplication led November This invention relates to coating devices,being particularly intended Vfor applying a coating of liquid, such as aliquid cement, to toe stifeners prior to their vincorporation in shoeuppers. The embodiment of my invention shown and described herein iscapable of holding a considerable supply of cementitious material and ofapplying it evenly to the marginal vportion of toestiffeners or other 1osimilar articles. A positively driven Wheel or roll is'used to feed theadhesive from the container and an adjustable auxiliary roll is suppliedto insure a firm engagement of a toe stifener with the feeding wheel andthus to insure a thorough and even application of the adhesive to thetoe stiifener.

An advantageous feature' of the device is found in the use ofthe'removable lid of the container as a support for ythe rolls. Thispermits easy access to the container for cleaning or refilling. Y

For amore complete understanding of the structure of the device,reference may be had to the drawings in which Figure 1 is a sideelevation of the device. Figure 2 is a section on'the,line 2-.-2 ofFigiure 1.

Figure 3 is a plan view.

Figure 4 is a longitudinal section on the line 4--4 of Figure 3.

Figures 5 and 6 are sections on the line 5-5 of Figure v4 showing theparts in two positions of adjustment. y Y

Referring in detail to thefdrawings, 10 represents a container of aconvenient size vfor a suitable amount of cementitious material or otherdesired coating compound.y A heating device 11 may be supplied to keepthe coating material in proper condition. This heating device may be ofany convenient desired construction, herein shown as of the electricalresistance type. At'one end of the container abracket 12 `is formed on'its outside surface'in which is journaled a power shaft 13. Fixed tothe power shaftv is a suitable pulley or sprocket 14 which may beconnected as b-y a belt or chain to any suitable source of power. 13 andis adapted to engage with a worm gear 16 secured as by a set screw 19 toone A worm 1'5 is also fixed on the shaftv 12, 1925.

end of a shaft 18. The container 10 is preferably supplied Withaseparate removable cover member or lid 17 in which is journaled theshaft 18. The worm gear 16 may be protected by a hood 20 preferably madeintegral withfthe lid. As shown in Figures 1 and 4, the end of the shaft18, which carries the gear 16, projects out beyond the end of thereceptacle 10 so as to permit the gear 16 to mesh with the worm 15 whenthe lid is in place. On the inner end of the vshaft 18 is mounted a feedwheel 21. This wheel is secured for rotation with the shaft 18 as by akey 22 and a' thumb nut 23, which permits ready removal of the wheelfrom the shaft. The wheel 21 is preferably provided with a relativelybroadrim 24 which extends downwardly to a point near the bottom'of thereceptacle and upwardly out through an opening 25 in the'lid. AsWill'readily beseen, rotation of the wheel 21 will cause the rim 24 topick up a film of the coating material Contained in the receptaclevlO'and carry such coating Vmaterial outside of the receptacle where it'may be applied to work brought in contact with the rim. In order toregulate the quantity of coating material to be ap.- plie'd to the Work,a scraper is mounted on the `lid`17 and is provided with an vedgeadjustable to any desired clearance from the rim 24 of the feedWheel'21. This scraper may comprise a spring member 26 secured to theunder surface of the lid 17. A scraping edge- 27 is provided on thespring member 26 and is positioned so as to have an even clearance fromthe rim 24. This clearance may be increased or diminished as by a setscrew 28 which maybe threaded through a lug 29 depending from the underside of the lid 17. A suitable slot is provided inthe rim of thereceptacle 10 to receive thek setv screw 28 when the lid is put inlposition. i

An idle wheel 30 is provided to cooperate with the feed wheel 21 byholding work which is passed between the two'wheels in closeengagementwith the feed wheel'21 so as to insure a complete Aandthorough coating of the work. This-idle wheel is rotatably mounted on areduced extension 31 on a stud shaft 32, the axesloffthe shaft and itsextension being eccentric to each other. The stud shaft 32 is held in alug 33 formed on the upper surface of the lid 17 as by a set screw 34,which is threaded through the upper end of the lug 33 and engages thestud shaft 32 in an annular recess 35. As shown in Figures 5 and 6, theset screw 34 may be loosened, permitting the angular adjustment of thestud shaft 32 in its bearing, which by reason of theeccentric positionof the extension 31 willdetermine the location of the wheel 30 relativeto the feed wheel 21. Thus the clearance between the rims of the feedwheel and the idle wheel is capable of fine adjustment. vThe surfaces ofthe rims of the idle and feed wheels are preferably of frusto conicalshape,'the pitch of the surfaces being so related to the'an'gularrelation between the shafts on VVwhich the vwheels are mounted that theclearance or space between the rims of the wheelsv will taper slightlyasindicated in Figures 1 and 4.

'The marginal skived or tapered portions of toe stifl'eners or othersimilar articles to be coated may. thus be pressed firmly into the spacebetween the wheels, while 4the rotation of the positively driven feedwheel will move the work along-and deposit a coating'of liquid asdesired. `4

The idle-wheel 30'may be mounted on its shaft in any desiredway. Asshown it is held 1n place by a machine screw 45 threaded into the endofthe shaft extension 3l and pro- VVvided with a head large enough tooverlap the end of the shaft and thus hold the wheel in place. A plug 36may be inserted in the hubof the wheel to cover thescrew 35. An oil port37 may be provided in the lid 17 to insure proper l'lubrication of theshaft 18. On the under side of the lid 17, a rim 38 is preferablyprovided near the margin of the lid to fit within the edges of thecontainer' 10 and hold the lid .in position` Ify desired, any suitablestraps or clamps may be used to hold the lid firmly in place when thedevice is in use.

It will readily be seen from the foregoing description and thedrawingsthat the device is simple and effective and is capable of beingtaken apart quickly and easily for cleaning or adjustment.
